It is my understanding though, based on what you're written here, is that this problem won't go away, and that is, basically (and a simplified explanation to people who may not be as technically inclined), an artifact of the software and the mathematical method used to solve the problem with a GPU.


Would that be a fair and correct summary of the root cause of it?


i.e. a better GPU with more VRAM will only make the "cubes" smaller, but it won't get rid of the non-physical flow that's observed in these CFD simulation results
